Bohdan Tymkiv 4440bf1fcd psoc6: Run flash algorithm asynchronously to improve performance
Existing psoc6 driver starts flash algorithm for each Flash row. This is
suboptimal from performance point of view, starting/stopping flash
algorithm for each row adds significant overhead. This change starts
flash algorithm and leaves it running asynchronously while driver
performs flash operations.

Performance gain is 170...250% depending on probe:
